Mikoto works there too! Obviously his uniform is different but the female uniform is... vaguely maid-esque?

There's also an actual butler and maid service in town. Which I think Usui would be even more interested in, because. Actual maids.

And Chiaki is a walking spoiler bomb for her canon, so! I try to avoid most spoilers but I might end up accidentally giving some hints towards something vaguely different about her from the other characters as school starts in Holly Heights...
